GIL VAPORIZEB. AND BUR-NER.

Burners, of which the following is a full,

clear, and exact description, reference being had to the accompanyingdrawings, form inga part of thisspecification.

This invention relates to apparatuses for burning oil, and especially tothat class of oil burners where the oil is converted into vapor by meansof heat, previous to burning; and has for its object to provide a burnerof a simple construction where the.

heat or the flame produced by the burner itself, is utilized ior'heatingthe oil previous to burning.

A further object of this invention is to provide a disposition of asimple character,

whereby the oil is forced to remain exposed for a certain length of timeto the heat of the flame before being fed to the burner, thus insuring athorough -vaporization of the same without the need of any otherauxiliary means, and insuring the production of a practically dry vaporunder considerable pressure.

A still further object is to provide an improved construction of burner,whereby, the oil vapors fed into the same will be readily andsimultaneously distributed through all the various parts of the burner,thus insuring an even intensity of flame at all points.

Oil burners of the type usually installed in steamships,'locomotives,and for the op eration of boilers of diiterent kinds, are rathercomplicated in design; and are generally based on the mechanicalatomization of the-oil. This requires air or steam 1111- a seriousinconvenience; but the main source of the inconvenience to be found inthese burners lies in their imperfect combustion; the combustiblematerial not being completely burned, produces dirt and refuse,

which accumulates in the burner, plugging the holes, and sometimesentirely stopplng its operation. When burning heavy crude oilsespecially, these burners prove most incflicient, and are liable to getplugged quite often; so much so, that the boiler installation is usuallymade much larger than necessary, in order to put a set of boilers intouse while another set undergoes a thorough Specification of LettersPatent.

cleaning of the burners, andof the atomizing appliances. I

In my improved device, the oil fed from a storage tank under a limitedpressure is compelled to travel n a coiled pipeof considerable length,which is exposed to the direct action of the flame, and it is thusheated and perfectly vaporized before reach. ing-the burner. The oilvapor th us'formed comes out absolutely dry, at a .iigh pressure, andboth these qualities insure a properly clean burner at all times.

Referring to the drawings, Figure l is. a perspective view of myimproved burner with regulating-valve; Fig. 2 is a sectional plan viewof the same, showing in detail its construction; and Fig. 3 isa sideview in elevation, partly sectioned,ot the-same. 1 The apparatus iscomposed of a burner proper, a feeding andvaporizing coil, and ayregulating valve. The burner is composed of an inlet pipe l, leading toa distributing ohamber 2, from which depart a number of tubes 3,provided with many small holes 3' their free ends by an enlargedchamberon collector 4, a. At each end of central chamrais s ret. s,iois. I

.80 on top, distributed over all the surfaceiof the burner. The drawingsshow two rows of? tubes, one on each side of the chamber 2,,

her 2 1 provide acover 5, removable, but, which must be normally tightlyfixed in a place, to prevent the escape of vapors; and at each end ofchambers, 4, I provide a similar .cover 6, for the same purpose, thisdisposition being most convenient for an ac casional cleaning. of theburner.

The main advantage'ot this form of burner is the si-:- multaneousdistribution of the oil vapors to all the tubes, which insures an evenintenr.

sity of flame at all points.

In the preferred form of construction of I I my device, to part 2 isclamped or otherwise attached a hollow part 7 by means of part 9; part 7is provided at the two ends with two hollow uprights 8, 8', not indirect communication with the inside of part 7 all these parts beingsubstantially built, and i i made of a good heat conducting material.

.Upright 8 is fitted with the feeding pipe 10, coming from the source ofsupply, and

upright 8 is fitted with pipe 11, leading to the regulating valve 12,which opens right in front of inlet pipe 1. Part 7 is mounted,

as shown, above burnenand the communi- I cation between uprights 8..andS'Liis estab lished by means of a flat coil 13 having a number of turnsdisposed around the center, and havingiits inner end attached to point14- of upright 8", and its outer end attached to point of hollow part 7and by means of a similar coil 13' attached at 14: to upright 8 and in15 to part 7. These coils 13, 13 are held at a certain distance from theburner, so that the flame issuing 0 from the latter can heat the formerand .Parts 7, 8, 8', and 9, will contribute to keep coils 13, 13 at ahigh temperature,

a the same being substantially built of a good g0 heat conductingmaterial for the purpose 30 around all the turns of the same, and at 14:

of storing heat.

Valve 12 can be of any suitabledesign, provided the same be capable ofgiving a good regulation.

The oil fed with a moderate pressure through pipe 10 to 8', enters coil13 at.

point :14, goes around all the turns of the same, then it enters thehollow space of part ,at l5; at 15' it enters coil 13, it goes it entershollow upright 8, and is led throughpipe 11 to regulating valve 12. The

vapor escapes from valve 12 at a. considerable pressure inthe directionof inlet pipe 1, through which it travels to chamber 2 to be distributedto all tubes 3, coming out from holes 3', when it is ignited.

When the burner is in operation, the oil vapors in the piping willproduce a back pressure, audit will then be necessary to increase thepressure of feeding to a point sufiicient to counterbalance the same,and the frlictional resistance opposed to the flow of 01 Tostart theburner, it is necessary first to heat the coils and the part 7sufficiently to produce an initial vaporization of the oil, and. thiscan be done either by temporarily installing an alcohol burnerunderneath,flor by feeding a combustible gas to the inlet pipe 1,through a separate source, or in any other suitable manner. Parts 7, 8,and 8, not to be essentially of the shape shown; the same beingsubstantially bui t of. a good. heat conducting material, will help inheating coils 13, 13, and in maintaining'the heat in the same.

I am. aware that the vaporization of the oil previous to burning bymeans of the flame issuing from the burner itself, has been used in manytypes of burners; in some of these however, the mechanical ar rangementis rather inefficient, with the consequence that the, vaporization ofheavy oils is only imperfectly obtained. This is someroaasra times dueto the fact'that the distribution of vapors in the burner takes placefrom This disposition gives an intensity of flame always decreasing asthe combustible gases progress through the passages, with the additionalinconvenience that at a certain tically the same time, producing an'evenheight and intensity of flame at all .points. Especial importance isattached to thefact nection with my presentdevice, are held above theburner at a distance from the same. This gives free access to airunderneath the coil, therefore permits the combustion of the oil vaporsissuing from said part of the burner, to properly take place. Owing tothis disposition, the vaporizing coil is at the same time exposed to thehottest part of the flames, and the va orization induced in the samewill there ore be more rapid and complete. The peculiar shape of thevaporizing coils is also partly responsible for the excellent resultswhich can be obtained with my improved burner; in fact, the same beingWound with several convolutions in the same plane, for a very longpassage exposed to the heat of the flames, through which the coil hasthe ossibility of being. thoroughly vaporize the various convolutionsare close one to the other, as shown in the drawing, there is theadditional advantage that only part of the flames are concealed fromdirect action on the boiler, and that radiation of heat from thevaporizing coil is very much re-[ duced.

My invention can be modified in many of its details without departingfrom the fundamental idea, governing the same; and

device such modifications and improvements which may properly enterunder the scope of my claims. 1
